ALBERT CARTER, OF FORESTVILLE, CONNECTICUT.

ODOMETER.

Specification of Letters Patent No. 16,008, dated November 4, 1856.

To all whom it may concern:

Be it known that I, ALBERT CARTER, of Forestville, county of Hartford, ancLState of Connecticut, have invented a new and useful Improvement in Odometers for Indicating the Distance Traveled by Carriages; and I do hereby declare that the same as described and represented in the following specification and drawing is sufiicient to enable others skilled in the art to make and use it.

I will proceed to describe the construction and referring to the drawings in which the same letters indicate like parts in each of the figures.

The nature of my invention consists in arranging the several parts in a compact form, so as to be easily attached and removed to or from the axle, at pleasure, by removing the wheel from the axle and tightening, or loosening the set screws by which it is secured.

In the accompanying drawings is shown at A Figure 1, the inside arrangement consisting of two round parallel plates having a collar C, on each of them.

D, is a ring closely fitted between the plates A, A, and the collar 0, C. E, E, E, E, are screws for the purpose of securing the apparatus to the axle B, the heads of which are made broad and fiat so that when they are turned down onto the axle the apparatus will be securely fastened thereto until it shall be desirable to remove it therefrom. Said screws are fitted into the ring D.

F is a spring with a catch on the end fitted and secured by a screw into the periphery of the ring D, and recessed in such a way as to allow the catch to be pressed down even with the surface, just above the spring F, and around the periphery of the ring D, is arranged a train of wheels consisting of a click wheel Gr, which as it revolves over the spring catch H, is caused to move one notch and held by the click I. The other wheels are calculated in such a manner as to show by the long pointer on the dial miles or fractional parts of a mile, and the short pointer tens or hundreds of miles.

y, Fig. 3, shows the arrangement of the dial on the outside which is designed to be locked in by a cap which covers and makes tight joints from dust, &c.

a, Fig. 2, is one of the parallel plates showing the collar C, which is turned over onto the work, Fig. 1, and inclosed by a ring or sheath 7s, fitting tightly over the edges and secured by a flange as shown at 7:, Fig. 5, on one side and by screws on the other side.

Fig. 6 is a vertical section through the center of odometer, hub and axle, exhibiting the operation of the pin in the hub upon the corresponding pin Z of the odometer. Z, shows a projecting pin secured on the revolving case as shown at Z, Figs. 4 and 5, which is operated upon by a corresponding pin of fiat surface driven or secured in the hub of the wheel designed to operate to move forward the apparatus, reference being had to the diameter of the wheel, which may be said here this apparatus is designed to be made to use with wheels of the ordinary size. Should the wheel be turned backward, it will be seen that the rachet wheel will slide over the spring catch without altering the notation on the dial plate 3 B, shows a section of the axle on which the odometer is attached. I intend also to attach a bell arrangement to note each mile as it is gone over by the carriage.

I do not confine myself to the particular manner described, in manufacturing, as it may be thought best to adopt a different way of putting the cases together, in order more cheaply to manufacture them. The objections ofiered to those heretofore made are their great expense, also the trouble and expense of attaching them to the carriage, and removing when not wanted, and being of so great an objection, as to prevent in a great measure, their introduction and sale. These can be manufactured at comparatively low prices, and five minutes is all that is required to put this on or take it off at any time.

What I claim as my invention and desire to secure by Letters Patent, is

The bearing ring D, the catch spring F, and the set screws E, on which the case containing the movements turn by the action of the carriage wheel, and produces the result of indicating the distance traveled in the manner and for the purpose as herein set forth and described.

ALBERT CARTER. [L. s.]
